Abstract

L'invention concerne un dispositif permettant d'émettre dans un système de communications numériques un multiplet partiel en position terminale de la zone d'information. Un message, non-pour-multiplets, pour multiplets, peut donc être mis en bloc de multiplets ayant toute dimension convenable, et, s'ils ne remplissent pas le multiplet final, les bits terminaux peuvent être acceptés tout en conservant la capacité de multiplet partiel. La dimension du multiplet final est indiquée, dans la mémoire, par l'adjonction d'un bit indicateur de caractère. Le caractère partiel est justifié à droite dans son multiplet, un à un - c'est-à-dire le bit indicateur - est inséré à la gauche du caractère, et des zéros sont ajoutés à sa gauche pour compléter le multiplet. Ce multiplet est placé dans un registre d'émission; un multiplet partiel est décalé à droite jusqu'à ce qu'apparaisse dans le registre une figure de tous zéros suivis d'un un. Cette figure est reconnue par le matériel et indique que la fin du multiplet partiel a bien été transmise. Pour les données reçues, on utilise le même traitement, inversé
